Why would some genes have more than two modes in their expression distribution? What external factors would cause this anomaly?
I'm referring to the expression distribution of a gene across different ...

Ordinal response variables show up often in biology, but I'm not sure how they are best analysed. Some examples are qualitative assessments (little, many, a lot) or risk assessments (low risk, medium ...

This basic evolution theory question has been haunting me since childhood and I'm kind of embarrassed that I can't explain it yet:
Consider a butterfly. It's wings have evolved to look like the eyes ...

I am in great need of help in order to infer the statistical hypothesis tests performed in an old paper. However I need to make some reasonable guesses only from the abstract of the paper since the ...

this simulation, you sampled the gene pool without replaceing beads in the beakerafter you drew each one. Thus, f(A) and f(a) in the gene pool changed slightly after each bead was drawn. For example, ...

Approximately, how many families have been identified?
I've often often come across figures for the total number of species on Earth. Recently, I found myself wondering about the encompassing ranks ...

I'm at the moment analyzing cytokine array data. The available material on the statistical analysis of these data is more than unsatisfactory. Since a lot of effort is being made in the analysis of ...
